INVENTOR:

By his Aflomey CHARLES-E. M MA iis, OF NEW YORK, N. Y.

, BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed June 3, 1906. Serial No. 263.607.

To all whom it may concern: Be it known that I, CHARLES E. MGMANUS,

a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in-Bottle-Closures, of

which the following is a specification.

This invention relates to bottle-closures or. the like.

The object of the invention is to improve the construction of the bottle-closures ormirig the subject-matter of United States Patents Nos. 762,745 and 772,250, granted to me June 14, 1904, and October 11, 1904, respectively.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts-and inthe details of construction hereinafter-described and. claimed as a thereof.

In the accompanying drawings, part of this s practical embodiment forming eolfication, Figure 1 is a side elevation of t e u per portion of a bottle or, jar with the cap e evated thereabove. Figs.

2, 3, 4, 5, 6, 7, and 8 are similar views showing the different forms of bottles or jars to which the invention can be applied- Fig. 9 is a perspective view of the cap. I

Like reference -numerals 1ndicate'corre aponding parts in the different figures of, the

rawmgs.

In the bottle-closures forming the subject-' matter of my prior patents the internal projections or lugs ofthe cap same are. passed through a num er of inclined grooves until they engage the under edge 0 a' straight or horizontal shoulder. The objection to these forms of closure is that after the lugs have been moved into engagement withthe under edge of the straight shoulder it is impossible to tighten the cap any further upon the bottle in the event that such further tightening should be necessary. By means of my present invention I overcome this objection by dispensing with the use of the horizontal shoulder and employing a shoulder having a gentle downward incline, so that after the lugs or projections of the cap have been passed through the sharply-inclined grooves of the neck and have. engaged the gentl -inclined shoulder the cap may be tightene to any desired extent by merely rotating the same.

In order that my invention may be more of a bottle, jar, or other suitab which may be of any desired form, as indiin ap' lying theclearly understood, I will describe the same with particular reference to the accompanying drawings.

The numeral 1 indicates the upper portion e receptacle,

cated in the drawings. The neck or extreme u per end of the receptacle 1 is formed exterior y with a plurality of downwardlyextending grooves 2, which are widened at their'upper ends, as shown in the drawings.

The, ooves 2 serve to produce a plurality of "shou ders 3, which extend downward on a sha incline and merge into gently-inclined shou ders 4. If desired, an annular shoulder or collar 5 may be formed on the receptacle below 'the shoulders 3 and 4,the lower end of each of the shoulders 4 terminating a slight distance above the shoulder 5, as shown clearly in Fig. 2.

The cap 6 may be of any suitable formand construction having. inward projections or lugs 7, which are adapted to engage the shbul ders 3 and 4 and constitute means to lock the ea in position. n applying the cap to the bottle or jar the fiared or widened upper end of the grooves 2 facilitates the entry of the projections7. The first turn of the cap 6 serves to move the rojection 7 along the sharplyinclined shoulders 3 until they engage the ently-inclined shoulders 4. The cap may-t en be locked with sufiicient tightness upon the bottle.

The lower end of each of the shoulders 4 preferably is disposed sufficiently near to the annular shoulder 5 to prevent the cap from being turned so far that the projections 7 will pass the lower end of the shoulders 4.

From the fore oing description it will be apparent that I ave provided a bottle-clo-' sure which may ,be uickly applied and locked with any desire degree of tightness without danger of the same working loose, as would be the case if a spiral groove of unifcirm pitch throughout its length were emp oyed.

Changes in the precise embodiment of invention illustrated and described may be made within' the scope of the following claims without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is- 1. A bottle or receptacle having an exterior shoulder extending downward on a sharp incline and merging into a shoulder having a incline and merging into a gentle incline,

a =lhorizontal' shoulder disposed below the gently-inclined shoulder, and a cap having an inward pro'ection of sufficient thickness to prevent it om passing beyond the extreme ends of said shoulders.

A bottleior receptacle having external shoulders each extendingdownward on a sharp incline and meshing into a entle incline, an annular shoulder disposed elow the gentlyinclined shoulder, and a cap having inward pro'ections, of suflicient thickness to prevent them from passing between the ex- ,treme lower ends of the gently-inclined shoul ders and the annular shoulder.

44, A ot recep acle provided with.eX-'

ternal grooveshavingflared upper ends, said grooves producing a-plurality of shoulders extending downward on a sharp incline and merging into a plurality of shoulders extending downward on a gentle incline, and a ca h'aving inward projections to engage the shou ders, said projections being of sufficient thickness to prevent them from passing between the extreme lower ends of the gently-inclinedshoulders and the annular shoulder.

5. Abottle or rece tacle havin .-,a neck formedwith exterior s oulders, eac extend- .ing downward on aisharp incline and merging into a shoulder having a entle incline, an annular shoulderdisposed elow the lower endofthe gently f-inclined-shoulders; and a cap having inward projections of-sufiicient thickness .to prevent them from passing between theextreme lower ends of the gentlyinclined shoulders and the annular shoulder.

6. A. bottle .or-greceptacle provided-with spaced enlargements producing intervening grooves, said enlargements being formed with gently-inclinedbasal shoulders and sharply- ,inclined end shoulders merging at their lower .endsinto said gently-inclined shoulders; said sharply-inclined endishoulders being approxi -mately coextensive in-depth andshaped. to

flare orwiden the upper entrance-ends of the grooves, and .a .cap provided at its lower edge :lvith'projections to cooperate with said shoulers.
